Mountain Pine Beetle Epidemiology in Lodgepole Pine
The following brief synthesis of mountain pine beetle epidemiology is based on host-beetle interaction. In the first part I briefly describe the relationship between the dynamics of lodgepole pine and mountain pine beetle. The second part describes the phases in the infestation cycle and their main characteristics. This synthesis is based on published information on infestation behaviour in wes...
متن کاملA structured threshold model for mountain pine beetle outbreak.
A vigor-structured model for mountain pine beetle outbreak dynamics within a forest stand is proposed and analyzed. This model explicitly tracks the changing vigor structure in the stand. All model parameters, other than beetle vigor preference, were determined by fitting model components to empirical data. An abrupt threshold for tree mortality to beetle densities allows for model simplificati...

متن کاملClimate influences on whitebark pine mortality from mountain pine beetle in the Greater Yellowstone Ecosystem.
Extensive mortality of whitebark pine, beginning in the early to mid-2000s, occurred in the Greater Yellowstone Ecosystem (GYE) of the western USA, primarily from mountain pine beetle but also from other threats such as white pine blister rust. The climatic drivers of this recent mortality and the potential for future whitebark pine mortality from mountain pine beetle are not well understood, y...
متن کاملMapping Percent Tree Mortality Due to Mountain Pine Beetle Damage
The mountain pine beetle (Dendroctonus ponderosae Hopkins) is a pervasive and particularly destructive species of insect that has killed vast areas of conifers in western North America. To map large areas of infestation satellite imagery is often used because of its ability to cover large areas, but the spatial resolution often precludes fine-scale analysis. Furthermore, maps of insect-caused t...
